The Folomatic is a control option allowing remote IQ operation from a proportional analogue control signal. Check IQ wiring diagram for Folomatic Control Option inclusion.

Get Settings
Loads the current Folomatic settings into the page for viewing, editing and saving to file.
Send Settings
Sends the Folomatic controller settings, as shown on the page, back to the Folomatic. Once sent, these settings will become the settings used by the Folomatic in operation.
Note. The setting of low and high set point positions is independent of the Page Send Settings control. Refer to Valve Position Set Points.

Save Folomatic settings, as viewed on the page, to file for future reference.

Folomatic Feedback. If an increasing value set point signal corresponds to the IQ opening the valve, select Valve Opening. If an increasing value set point signal corresponds to the IQ closing the valve, select Valve Closing.
Note Changing the Folomatic Feedback setting will also effect the IQ Option - CPT (current position transmitter) feedback. Refer to CPT.
Set Point Signal Type. If the applied signal is a proportional current signal type (mA), select Current I. If the applied signal is a proportional voltage signal type (V), select Voltage V.
Use the drop down box to select the range that encompasses the applied set point signal range.
Valve Position Set Points. Setting the low and high set point positions must be carried out individually. Page Control - Send Settings, does not include the low/high valve position set points.
Under Folomatic control, the actuator will move to the set low/high positions when the low/high signal is applied. The actuator will position in proportion to the applied signal between the low ant high set point positions.
Note. The set point signal value corresponding to the actuator being at the low position must be applied to the actuator when setting the Low position. Apply the signal, use the slider to set the required low position and then use the Set Now control.The set point signal value corresponding to the actuator being at the high position must be applied to the actuator when setting the high position. Apply the signal, use the slider to set the required high position and then use the Set Now control.

Deadband
If the actuator hunts or responds unnecessarily to a fluctuating set point signal the deadband must be increased. The minimum deadband setting will be a function of set point signal fluctuation and/or overshoot/undershoot which in turn is a function actuator speed, valve stiffness and backlash etc. To maximise valve and actuator life, set the deadband to the widest value possible while maintaining acceptable control. If more accurate control is required the deadband may be decreased.
Refer to Folomatic Monitor.
Back to IndexMotion Inhibit Timer (MIT)
The motion inhibit timer introduces a delay in the actuators response to a rapidly fluctuating set point signal, preventing unnecessary movement. Once the system stabilises the actuator will respond to steady changes in set point signal as necessary. To maximise valve and actuator life, set the Motion Inhibit Time to the longest time possible while maintaining acceptable control.
Warning Setting the MIT to a short or zero time may cause the actuator to exceed its motor rating.

Action on loss of set point signalThis feature is only available for control systems using an offset or live zero signal range, for example 4 - 20mA.
Use the drop-down to select the required action.Notes: The signal is "lost" when it reaches approximately 50% of the set minimum position value, i.e. on a 4 - 20mA system the signal is "lost" at approx. 2mA
Caution: If Feature inhibit is set the actuator will move to a position proportional to the low set point signal position which may not correspond to the set low set point position. It is recommended that feature inhibit is not used when a specific action required. Choose the required action from the drop down box.

Run/Stop
Use this control to start/stop real time monitoring.
Note. When monitoring, there is a small delay in updating the information shown by Insight due to transmission delay over the I-R interface.
Back to IndexPosition
Indicates the demand set point and IQ feedback in graph and digital % readout forms. The error is the difference between the two.
Note. The readouts are in terms of % of applied signal and position range, 0% being the set low signal value at the set low signal position. Refer to valve position set points.
Back to IndexStatus
Operate Mode
Auto - Analogue control is active, digital control is disabled.
Hand - Digital ("pushbutton") control is active, analogue control is disabled.
Note. Refer to IQ wiring diagram or publication E120E for details of hand/auto control.
Back to IndexMotion Inhibit
Active - the Motion Inhibit Timer (MIT) is active. The MIT timer prevents operation while active. Refer to Actuator Response, Motion Inhibit Timer.
Inactive - the MIT is inactive. The actuator will respond to the next change in demand set point outside the set deadband.
Back to IndexInput
In range - the applied set point signal is within the range set between low and high set point positions.
Lost - Low demand set point signal lost, substitute move to Low set point position.
Lost - Stayput demand set point signal lost, substitute Stayput
Lost - High demand set point signal lost, substitute move to High set point position.Note. IQ will respond as set for the action on loss of set point signal.
Refer to Action on Loss of Set Point Signal
Back to IndexRequest
The difference between demand and feedback will generate an action request:
Hold - no action. The error between demand and feedback falls within the set deadband range.
Open - move open The error between demand and feedback falls outside the set deadband range and is of a magnitude requiring a open action in order to reduce/cancel the error.
Close- move close The error between demand and feedback falls outside the set deadband range and is of a magnitude requiring a close action in order to reduce/cancel the error
